| 摘 要： | 为克服在利用传统自适应边界元法求解弹性问题时需对不同问题设计不同误差估计公式的缺点,以专家经验为基础,利用模糊逻辑理论,提出一种新的误差分析方法.基于H-R自适应边界元法,用FORTRAN编写求解2个经典平面弹性静力学问题的程序.分析表明该误差分析方法能较好地估计边界元解的误差.

| Abstract: | To overcome the shortcoming of the traditional adaptive boundary element method which needs different error estimation formulae for different problems, a new method of error estimation is proposed by expert experience and fuzzy logic system. Based on H-R adaptive boundary element method, FORTRAN is used to develop a program to solve two classical plane elastostatics problems. The analysis indicates that the method can effectively estimate the error of boundary element solutions. |
